Working Principles

efficient classifier (powder concentrator) is a novel efficient classifier which uses the air eddy in the powder concentrator on the horizontal direction to classify the materials. The formation of flow field and the classifier principle are greatly different with centrifugal classifier and cyclone classifier. Now it is widely applied to classify the soft materials roughly because of its better performance and notable production-increasing and energy-saving effect compared with the conventional powder concentrator, and efficient classifier is regarded as the typical representative of the third generation of efficient classifying equipment.

Equipment Characteristics

1. Classifying airflow can enter from two sides horizontally; and because of the action of guide blade and horizontal separating plate, the airflow only rotate crosswise, that is recycles in horizontal plane whether in the ring classification area or the turbine classification area.

2. Materials can be scattered preferably under the action of scattering plate and buffering plate, and fall into the ring classification area to meet the steady classification airflow, so that the gas-solid mixture can be uniform, and gas-solid ratio is higher.

3. Materials fall vertically through the whole classification area, and stay for a long time during the process, so as to be classified for many times.
